I am not collecting them, at least not yet. These seem a little more on the OF side of the fence than PCI. They are a little intertwingled with the sparc PCI bridge window issue, and Ben has some concerns, so maybe we'll have to figure out what makes the most sense when that gets sorted out. I'm still curious whether all these functions can be consolidated. If that's possible, it would be much nicer than having to fix all the copies.
